我花了几个小时搜索这个错误,我几乎测试了它在Google上的所有内容。
我想在C#中使用TCP,.NET4和VS2010访问服务。
我有一个非常小的服务:
namespace WcfService_using_callbacks_via_tcp
{
[ServiceContract(CallbackContract = typeof(ICallback), SessionMode = SessionMode.Required)]
public interface IService1
{
[OperationContract]
string Test(int value);
}
public interface ICallback
{
[OperationContract(IsOneWay = true)]
void ServerToClient(string sms);
}
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
public class Service1 : IService1
{
public string Test(int value)
{
ICallback the_callback = OperationContext.Current.GetCallbackChannel<ICallback>();
the_callback.ServerToClient("Callback from server, waiting 1s to return value.");
Thread.Sleep(1000);
return string.Format("You entered: {0}", value);
}
}
}
使用此Web.config:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />

<system.serviceModel>
<services>

这个代码来托管它:
static void Main(string[] args)
{
Uri base_address = new Uri("net.tcp://localhost:5050/Service1");
ServiceHost host = null;
try
{
// Create the server
host = new ServiceHost(typeof(Service1), base_address);
// Start the server
host.Open();
// Notify it
Console.WriteLine("The service is ready at {0}", base_address);
// Allow close the server
Console.WriteLine("Press <Enter> to stop the service.");
Console.ReadLine();
// Close it
host.Close();
}
catch (Exception ex)
{
// Opus an error occurred
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(string.Format("Host error:\r\n{0}:\r\n{1}", ex.GetType(), ex.Message));
Console.ReadLine();
}finally
{
// Correct memory clean
if(host != null)
((IDisposable)host).Dispose();
}
}
现在我想创建客户端,但我认为它不可行。我直接使用了Add Service Reference和svcutil,但是我收到了这个错误:

如果您需要更多帮助,请输入“svcutil /?”
所以,我可以毫无问题地托管服务,但我无法创建代理。
我已经尝试了几乎所有我发现的配置,但我认为当前的web.config是正确的。使用mex的行为,安全性和绑定由端点使用。
我尝试创建app.config并使用svcutil.exe将其设置为同一文件夹。
